The Lutron Caséta Diva smart dimmer brings smart control to a classic paddle-style dimmer. It needs no neutral wire, so it suits older homes. Use it at the wall, add a Pico remote for another control point without new wiring, or add a Lutron Smart Hub for app control, schedules and voice assistants. For 3-way or multi-location control, use the existing mechanical switch, Pico remotes or a Claro smart accessory switch. Wallplate sold separately.
